Has anyone installed a dual speed oven step-up? Or actually installed a Advantium 240 under the countertop (not approved in the manual...I know) We are planning a remodel and want 3 ovens, a large Monogram French door oven and 2 Advantium speed oven, so we always have access to a speed oven and a microwave at the same time with the flexibility to do 2 speed ovens if we need it. And because the forums seem to indicate the 120 Advantum is pretty weak, and it's only $500 less, we'd rather have the 240.

Option 1: We'd like to know if anyone has stacked 2 Advantiums (unapproved) Not sure why you can put it over a full size oven, but not another speed oven. With 2 Advantiums, we can move the French Door somewhere else on its own. The French door oven more of a showpiece oven anyway, and would look great at counter level.

Option 2: Stack the French door with an Advantium (GE approved) but then we need to find a home for the other Advantium, and what seems like it would be better under a counter. Unlike the French door, it's not as much of a show piece.

So, really wondering if others had gone with unapproved Advantium setups.
